DYEING APPARATUS FOR WOVEN FABRICS.

SPECIFICATION forming part of Letters Patent No. 460,024, datedSeptember 22, 1891. Application filed January 15, 18914. Serial No.377,891. (No model.)

T0 all whom, t may concern:

Be it known that I, GEORGE MoELor, of Paterson, in the county of Passaicand State of New Jersey, have invented a new and Improved DyeingApparatus for Woven Fabrics, of which the following is a full, clear,and eX- act description.

rlhe invention relates to apparatus for dyeing woven fabrics in thepiece.

The object of the invention is to providea new and improved dyeingapparatus which is simple and durable in construction and permits ofreadily and conveniently passing the fabric stretched in its entirewidth through the dyeing-liquid, so as to evenly saturate the bers withthe liquid to insure perfect work without any streaks whatever.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter fully described, and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the gures.

Figure lis a plan view of the improvement, and Fig. 2 is a sectionalside elevation of the same on the line line x x of Figi.

The improved dyeing apparatus is provided with a frame A, adapted to beset with its lower part into a vat I3, containing the dyeing-liquor. Theframe A is connected at its upper part by chains O with a suitablehoisting` mechanism for raising or lowering the said frame to set itinto or to remove it from the vat B. The frame A is preferablyconstructed with an upper rectangular frame D and asimilarly-constructed lower frame D', both being connected with eachother by suitable posts E.

In the upper part D of the frame Ais journaled a series oftransversely-extending shafts F, arranged parallel to each other in ahorizontal plane. Each of the shafts F supports between the side bars ofthe frame D a roller G, over which the fabric is adapted to pass. In thelower frame part D' are journaled similar shafts F', supporting` rollersG', under which the fabric is passed, as is plainly illustrated in Fig.2. As shown in the latter figure, the lower rollers G' are immersed inthe dyeing-liquid in the vat E, while the upper rollers G are in theopen air. The shafts F extend to one side of the upper frame D, and eachisv provided at its outer end with a sprocket-wheel H, the severalsprocket-wheels beingconnected with each other by a suitable endlesssprocket-chain I, as is indicated in Fig. l. On one of the shafts F isalso secured `a pulley J, connected by a belt K with suitable machinery,so as to impart a rotary motion to the particular shaft F, whereby allthe shafts F are rotated in unison by the action of the sprocket-chain Iand the sprocketwheels H. Above the two end rollers G are arrangedsimilar rollers N and N', secured on shafts L and L', respectively,mounted in suitable bearings erected on the upper part D of the frame A.

In order to tighten the fabric to be dyed, tightening-rollers O and Oare employed, located above the rollers G and between thc 2, the saidrollers O and O' being adapted to engage the fabric on the upper side.The tightening-rollers O and O' are secured on shafts P and P',respectively, mounted to turn yin bearings P2, fitted to slidevertically in brackets D2, erected on the side rails of the upper frameD. The bearings P2 are engaged by screw-rods Q and Q', respectively,mounted to turn in the said brackets D2, and serve to raise and lowerthe bearings and consequently the rollers O and O' to tighten the fabricto be dyed. Between these two tightening-rollers O and O' is arranged athird tightening-roller It, adapted to engage the fabric on the underside, as is illustrated in Fig. 2. This roller R is secured on a shaftS, also mounted to turn in bearings P3, fitted to slide vertically inbrackets D3, secured to the upper frame D. Screw-rods Q2 are mounted toturn in the said brackets D3 and engage the said bearings P3, in orderto raise and lower the roller R, so as to increase or diminish thedegree of tightening of the fabric.

The operation is as follows: rlhe woven fabric T is passed with one endfirst over one end roller G and then down under the first correspondingend roller G' in the lower frame part D'. From this first roller G' thefabric is passed upward and over the second roller G, then down andunder the second roller G', then up again, and so on over the severalupend rollers N and N', as is indicated in Fig.

. so as to meet the point of starting, at which point the ends T' of thefabric .are fastened together by sewing and other means. The fabric tobe dyed is thus formed into an endless belt stretched over and under theseveral rollers arranged inthe frame A. The frame A is now set into thevat B by suitable mechanism, as is previously mentioned. Rotary motionis now imparted by the belt K to the upper set of rollers G, as ispreviously described, so that the fabric passing over the ksaid rollersis caused to travel, and censequently in traveling under the rollers G'rotates the latter, as well as the rollers N N', O O', and R. Therollers N N' and the corresponding end rollers G may be fluted orcorrugated, so that the fabric passing between the said sets of rollersis pressed on to establish the necessary tension in order to move thefabric forward over the several rollers, as is previously described.

The tightening-rollers O, O', and R are adjusted by means of theirscrew-rods Q, Q', and Q2, respectively, to additionally insure atraveling movement of the fabric. The fabric is thus stretchedthroughout its entire width over the several rollers, and in moving fromthe upper rollers to the lower ones and from the latter to the upperones the fabric passes through the dyeing-liquid in the vat A, and thusbecomes impregnated with the dyeingliquid and consequently dyed. It willbe seen that in this manner the endless fabric may be passed as manytimes as necessary through the dyeing-liquid, so as to insure perfectdyeing of all the fibers in the fabric. As the fabric is stretchedthroughout its entire width and passed over the revolving rollers G andG', all creases and streaks so frequently occurring in dyeing wovenfabrics are avoided and a perfect even and uniform dyeing of the fabricis insured.

By imparting a rotary motion to the upper set of rollers all strain istaken off the fabric, so that the fabric travels easily, smoothly, andWithout undue stretching in any direction.

Having thus fully described my invention, l claim as new and desire tosecure by Letters Patentl. In a dyeing apparatus, a frame adapted to beplaced in a vat, provided with brackets projecting from its upper siderails, a series of rollers mounted between the upper side rails of theframe, a series of rollers mounted between the lower side rails of theframe, rollers mounted in the frame above the end upper rollers, andtightening-rollers adjustably mounted in the brackets, substantially asdescribed.

2. In a dyeing apparatus, the combination, with a frame and a series ofrollers mounted in the upper and lower part of the frame, of thebrackets D2 D3, proj eeting from the frame, the tightening-rollers O OR, mounted in bearings sliding in the said brackets, and the screw-rodsQ Q Q2 for adjusting the bearings of the said tightening-rollers,substantially as and for the purpose set forth.

3. An apparatus for dyeing, comprising a vat, a frame adapted to rest inthe vat, 'a sesies of rollers mounted in the upper part of the frame,aseries of rollers in the lower part of the frame, a roller mounted aboveeach end roller of the upper series of rollers, and tightening-rollersadj ustably mounted in the frame above the upper series of rollers,substantially as herein shown and described.
